Summary: The study found that the social diversity of bilinguals' language use is associated with executive control, but the direction of the effects may depend on social context. Some effects may only be detected by using more sensitive measures, such as pupil dilation.

Summary: This study investigated the impact of age of acquisition on second language proficiency using anatomical and functional Magnetic Resonance Imaging. It found that highly proficient bilinguals use a neural network associated with domain-general inhibitory processes when switching between languages, and proficiency rather than age of acquisition influences language representations.

Summary: This study investigates the influence of genes such as FOXP2, COMT, BDNF, and Kibra/WWC1 on bilingual language control. Statistical analyses show that these genes significantly affect neural coding and behavioral performance in language control. These findings suggest that bilingual language control is shaped by both an individual's experience switching between languages and their genetic makeup.

Summary: Using techniques such as functional magnetic resonance imaging (fMRI) and transcranial direct current stimulation (tDCS), researchers have found that in bilingual language production, the bilateral cerebellar lobules have different functions. The results indicate that the right cerebellum is more involved in language control, while the left cerebellum plays a computational role in cognitive control and connects with more areas of the brain.

Summary: This study investigated differences in memory performance between children, adolescents, and adults using fMRI and found that differences in executive rather than associative abilities explain these differences. The results suggest that children's executive system is not as mature as in adolescents and adults, and therefore cannot facilitate memory performance in the same way.

Summary: The study revealed that patterns of neural activity in frontal brain regions reliably distinguished between switch and non-switch conditions, with frontal and fronto-cerebellar connectivity identified as key components of the language control network. These findings further demonstrate the involvement of the cognitive control network in bilingual language production.

Summary: This study compared the connectivity of resting-state networks between participants with high and low working memory capacity. It found that differences in working memory capacity are associated with network connectivity variations in attentional control-associated regions during both resting and task performance conditions. The high capacity group showed stronger connectivity in attention control-related areas.

Summary: This study investigates the neural mechanisms of resolving response competition during bilingual word recognition, focusing on the impact of language intermixing. The processing of cognate words in bilinguals showed longer reaction times and greater activation in the SMA compared to L2 control words. Additionally, a significant effect of L2 proficiency was observed only in the SMA, supporting the task decision system's role in bilingual word recognition.

Summary: The study found that newly learned words in Spanish and English overlapped largely in brain regions, but differed in terms of cognitive control and phonological processing. Spanish showed heightened activity in the prefrontal cortex due to competition of existing lexical representations, while English displayed higher activity in the primary auditory cortex due to more irregular phonological-orthographic mappings.

Summary: The study found that higher proficiency in the second language is associated with better executive control performance, and bilingualism-related neuroplasticity may peak at a certain stage and eventually reverse. Experienced bilinguals optimize behavioral performance independently of volumetric variations.

Summary: The study compared brain activity in English monolinguals and Spanish-English early bilinguals during arithmetic problem-solving using functional magnetic resonance imaging. Results showed no effect of bilingual language experience on brain activity related to arithmetic, suggesting early bilingualism does not influence the neuroanatomy of simple arithmetic.

Summary: This study found that bilingual MS patients performed well in inhibitory control and monitoring abilities, while monolingual MS patients showed poor monitoring abilities. Bilingualism may counteract cognitive deficits related to MS, while the high monitoring cost in monolingual patients may be related to deficits in monitoring and switching abilities.

Summary: This study examines the metabolic correlates of experience-based brain adaptations using bilingualism as a case study. Results show differences in metabolite concentrations between bilinguals and monolinguals, with these concentrations correlating with the degree of bilingual engagement. This suggests that long-term cognitive experiences can influence metabolic concentrations at the cellular level, potentially driving macroscopic brain adaptations.

Summary: The long-term management of more than one language has been found to influence brain and cognition, particularly in older adults, where bilingualism can have protective effects against neurocognitive decline. This study investigates the potential effects of bilingualism on the hippocampus, a brain structure related to memory, in older individuals. The results suggest that long-term active bilingualism may have neuroprotective effects on the hippocampus.

Summary: This study investigates the non-linear effects of bilingual experiences on regional grey matter volume in the brain. The results show a non-linear relationship between bilingualism score and inferior frontal gyrus volume, as well as linear increases in putamen and cerebellum volumes as a function of bilingualism score.

Summary: Recent studies on the effects of bilingualism on cognitive abilities have produced mixed results, with this study finding that diglossia, a linguistic situation with two varieties of the same language, does not significantly impact executive functions in young adults. Limited opportunities for language switching may be a factor in these findings.

Summary: Bilingualism is associated with structural adaptations in subcortical brain regions, but studies on the specific locations and extent of these adaptations have yielded inconsistent results. This study found that the volumes of the bilateral caudate nucleus and nucleus accumbens were significantly related to bilingual experiences and followed a non-linear pattern. Additionally, the volumes of the putamen and thalamus were positively predicted by bilingual experiences. These findings provide direct evidence of dynamic and non-linear subcortical structural adaptations in bilingual individuals.

Summary: Studies on the role of dual language use in modulating executive functions have shown differing results, with some studies indicating benefits for older adults. These studies often focus on bilingual settings and rarely investigate dual language use in diglossic settings. In this study, the performances of three groups of older adults (Arab diglossics, bilinguals, and monolinguals) on tasks measuring inhibition and switching abilities were compared. The findings showed a diglossic benefit in inhibition, but no benefits were observed for the bilingual group. The implications of these findings are discussed in relation to conversational contexts in dual language use.

Summary: Bilingualism has been found to increase resilience against cognitive aging, but its effects on neurocognitive outcomes in individuals with Mild Cognitive Impairment (MCI) are still unclear. This study examines the impact of bilingual language experience on structural brain data in a cohort of bilinguals diagnosed with MCI. The results indicate a non-linear relationship between bilingual language entropy and hippocampal volume, although no significant effect on episodic memory performance or age of MCI diagnosis was found.

Summary: This study proposes a multi-penalized state-space model for analyzing unobserved dynamics, using a data-driven regularization method. Novel algorithms are developed to solve the model, and a cross-validation method is introduced to evaluate regularization parameters. The effectiveness of this method is validated through simulations and real data analysis, enabling a more accurate exploration of cognitive brain functions.
